Abstract

The present disclosure is directed to a plasticizer composition, polymeric compositions containing the plasticizer composition, and coated conductors comprising the polymeric composition. The plasticizer composition comprises an epoxidized fatty acid alkyl ester having an APHA color value of less than 100, a triepoxide content of at least 6.5 weight percent, and an oxirane oxygen content of at least 5 grams oxirane per 100 grams of epoxidized fatty acid alkyl ester.

First claim

The invention claimed is:

1. A plasticizer composition, comprising:
an epoxidized fatty acid alkyl ester, wherein said epoxidized fatty acid alkyl ester has
(i) an APHA color value from at least 1 to less than 15;
(ii) a triepoxide content from at least 6.5 weight percent to less than 8 weight percent, based on the entire weight of said epoxidized fatty acid alkyl ester, wherein the triepoxide is an epoxidized C18 fatty acid alkyl ester molecule having three epoxide groups on its alkyl tail;
(iii) an oxirane oxygen content of at least 5 grams oxirane per 100 grams of epoxidized fatty acid alkyl ester;
(iv) a fatty acid dimer content greater than 0.8 weight percent based on the entire weight of said epoxidized fatty acid alkyl ester; and
(v) an iodine value from at least 1 gram to less than 5 grams per 100 grams of epoxidized fatty acid alkyl ester.

2. The plasticizer composition of claim 1 , wherein said epoxidized fatty acid alkyl ester has a palmitate content from at least 10 wt % to less than 12 weight percent based on the entire weight of said epoxidized fatty acid alkyl ester; wherein said epoxidized fatty acid alkyl ester has a stearate content from at least 4 wt % to less than 5 weight percent based on the entire weight of said epoxidized fatty acid alkyl ester.

3. The plasticizer composition claim 1 , further comprising an epoxidized natural oil.

4. The plasticizer composition of claim 1 , wherein said epoxidized fatty acid alkyl ester has a fatty acid dimer content of at least 1.2 weight percent based on the entire weight of said epoxidized fatty acid alkyl ester; wherein said epoxidized fatty acid alkyl ester has a triepoxide content of from at least 6.5 weight percent to at least 7.0 weight percent based on the entire weight of said epoxidized fatty acid alkyl ester.

5. The plasticizer composition of claim 1 , wherein said epoxidized fatty acid alkyl ester further comprises fatty acid dimers in a concentration of at least 1.2 weight percent, based on the entire weight of said epoxidized fatty acid alkyl ester.

6. The plasticizer composition of claim 1 , wherein the epoxidized fatty acid alkyl ester has an oxirane oxygen content from at least 6.2 grams to up to 7.0 grams oxirane per 100 grams of epoxidized fatty acid alkyl ester.
